    Abstract Maize (Zea mays L.) A188 calluses derived from leaf tissues of in vitro grown seedlings were initiated and maintained on Murashige and Skoog medium supplemented with 2 mg/1 2,4-dichlorophenoxyacetic acid (2,4-D). The calluses produced green leafy structures and subsequently plantlets upon transfer to N6 medium containing 2 mg/1 2,4-D and 0.1 mg/1 zeatin. An embryo-like structure with a green prominent coleoptile and a scutellum-like body was also obtained.

    Abstract A series of D-π-A star-shaped molecules with triphenylamine (TPA) as a core, 1,8-naphthalimide (NI) derivatives as end groups, and different π-bridges have been designed to explore their optical, electronic, and charge transport properties as organic solar cell (OSC) materials. The calculation results showed that the star-shaped molecules can lower the material band gap and extend the absorption spectrum towards longer wavelengths. The designed molecules own the longest wavelength of absorption spectra, oscillator strength, and absorption region values. Our results suggest that the designed molecules are expected to be promising candidates for OSC materials. Additionally, the molecules with ethyne, thiophene, benzo[c][1,2,5]thiadiazole (BTA), and 2,3-dihydrothieno[3,4-b][1,4]dioxine (DTD) as π-bridges and 4-pyridne, 4-aniline, and H in NI fragments have better hole- and electron transporting balance and can act as nice ambipolar materials. The values of hole mobility of molecules with ethyne as a π-bridge and NI as an end group for Pna2(1) and P2(1)/c are 5.30 × 10(-3) and 1.27 × 10(-2) cm(2) V(-1) s(-1), respectively. On the basis of the investigated results, we suggest that molecules under investigation are suitable donors of [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) and its derivatives are acceptors of solar cells.

    Abstract Furrow irrigation in cotton growing vertosols is the most preferred method in Australia. After fertilisation, irrigation water interacts with the soil which can dissolve nitrogen (N) compounds into the run-off water. The run-off or tail water that leaves the field is enriched with N and can reduce crop N use efficiency. During 2014−2015 and 2015−2016 N solute concentration in the irrigation water and run-off was measured in a tillage cropping rotation experiment. In the continuous cotton treatments (2014−2015) when urea was broadcast on the surface of furrow irrigated cotton system, 11 % of the applied fertiliser (260 kg N ha⁻¹) was lost from the field in the tail water. Most of the losses from the soil occurred during the first irrigation as nitrate and urea. The irrigation water supplied 10 kg dissolved organic nitrogen (DON) kg N ha⁻¹ to the field. During 2015−2016, when subsurface banding of the urea was used, losses equated to 5 % of applied N, in irrigated continuous cotton treatments. In a second crop treatment, an irrigated maize rotation, the broadcasted urea was leached into the soil by rainfall before a 100 mm irrigation event. The run-off losses were less than the sub surface urea banding and in this treatment were 0.5 % of the applied fertiliser. The study shows that DON-N, NO₃-N, NH₄-N, Urea-N are dissolved from the soil in cotton production systems and lost to furrow irrigation run-off. This dissolved N maybe denitrified in the cotton irrigation network if the tail water is not reused quickly. The results show that N contributions from irrigation water need to be accounted for overall N budget of the cotton farm to improve the N use efficiency.

    Abstract Abstract: Objective To study the change trend, distribution characteristics and causes of medical malpractices in 18 years, through retrospective analysis of 1 900 cases of medical malpractices, in order to provide guidance for the precaution and the treatment of medical malpractices. Methods A thousand and nine hundred medical malpractice cases that were accepted by Hunan Xiangya Judical Identification Center from 2000 to 2017 were collected. Statistical analysis on the caseloads, the clients, the department distributions, the levels of the hospital and the causes of medical malpractices, etc were conducted. Results The number of cases commissioned by third-party accreditation agencies for medical fault identification was on the rise; The clients of medical malpractices changed significantly in 18 years. Most of the medical malpractice cases occurred in secondary and tertiary hospitals, significantly more in surgery, obstetrics and gynecology. The occurrence of medical malpractices was related to the doctor's insufficient prediction of the severity of the disease and the possible complications, and failure to fully inform the relevant duty of care, etc. Conclusion China's medical malpractice solutions and medical fault identification procedures are gradually improving. Strengthening the medical malpractice precaution awareness of medical workers in surgery, obstetrics and gynecology will be conducive to resolution of medical malpractices.

    Abstract North American horses are commonly exposed to Leptospira organisms. Leptospira Bratislava is the most common infecting serovar but this serovar has not been confirmed to cause clinical disease in North American horses. Leptospira Pomona type kennewicki is responsible for most of the clinical diseases (leptospirosis) in North American horses. Leptospirosis is most commonly associated with diseases of the placenta and fetus, the kidneys and the eyes in horses. In-utero infections in pregnant mares may result in abortion, neonatal illness or birth of an antibody positive healthy foal. Acute renal failure in younger horses and recurrent uveitis in adult horses are other well documented clinical syndromes of leptospirosis. Abortions, neonatal disease and acute renal failure are caused by a subacute infection, while horses with Leptospira associated recurrent uveitis develop ocular disease months or years after the initial Leptospira infection. Diagnosis of Leptospirosis is made by a combination of antigen or antibody testing methods. Mares that abort following Leptospira infection have no additional clinical signs at the time of abortion but may shed the offending Leptospira spp. in the urine for several weeks. Antibiotic treatments are sometimes used in hopes of decreasing Leptospira shedding in infected horses or prophylactically in exposed pregnant mares but documentation of efficacy is lacking. Horses with Leptospira - associated acute renal failure can be successfully treated with antibiotics and supportive care. Recurrent uveitis is commonly associated with leptospirosis in North American horses and although horses may have chronic intraocular infection triggering an immune disease, systemic antimicrobial therapy has not been effective in eliminating the organism from the eye. An equine approved Leptospira Pomona type kennewicki vaccine is now available in North America.

    Abstract Abstract: Objective The morphological data of the second thoracic vertebra and the third lumbar vertebra were measured by computerized tomography (CT). The sex differences were analyzed and the discrimination equation was obtained. Methods The data of 274 adults (203 cases from experimental group and 69 cases from validation group) from central China were collected. Four linear data (maximum transverse length of vertebral body, maximum longitudinal length of vertebral body, maximum transverse length of vertebral foramen, maximum longitudinal length of vertebral foramen), one angle data (angle between spinous processes) and two area (vertebral foramen area, total cross-sectional area of vertebral body) data of the second thoracic vertebra and the third lumbar vertebra were collected, respectively. Then three ratios [maximum transverse length/ maximum longitudinal length of vertebral body, maximum transverse length/ maximum longitudinal length of vertebral foramen, vertebral foramen area/ (total cross-sectional area of vertebral body-vertebral foramen area)] and one angle (angle between spinous processes) were obtained. The discriminant equation was established for sexual discriminant analysis. Results The morphology of the second thoracic vertebra and the third lumbar vertebra was related with gender. Four single index discriminant formulae and eleven multi-index discriminant formulae were established. The 69 validation group samples were substituted into the formula for testing, and the maximum discriminant accuracy rate of the single-index discriminant formula was 75%. The maximum discriminant accuracy rate of multi-index discriminant formula was 83%. Conclusion It is feasible to conduct individual sex analysis by the morphological indexes of second thoracic vertebra and the third lumbar vertebra. The indexes have important application values in practice.

    Abstract Objectives: To establish a mathematical model of stature estimation for Sichuan Han females on the basis of the relationship between lower limbs and individual height, thus to provide evidence for forensic identification.
    Methods: Samples were collected from 171 Sichuan Han females. Large flat panel multi-function digital photography system was used to take the full-body X-ray films of the lower limbs. Indexes of long bones and stature of the subjects were measured, respectively. A linear regression analysis was carried out on the correlation between them, and a mathematical model of the stature calculation was established. Then the mathematical model was used to calculate the stature of another 29 Sichuan Han females to test its accuracy.
    Results: The maximum length of femur (
    Conclusions: The stature estimation is high by using the long bones of the lower limbs has high accuracy.

    Abstract Background: Current serological tests cannot discriminate between bactericidal Borrelia burgdorferi antibodies from others that are merely a response to Borrelia antigenic stimulation.
    Objective: To develop a sensitive and convenient luminescence-based serum bactericidal assay (L-SBA) to identify serum borreliacidal activity.
    Study design: Prospective validation study and method comparison.
    Methods: Serum samples were obtained either from archives of the Animal Health Diagnostic Center at Cornell University (N = 7) or from a vaccination trial (N = 238). Endogenous complement-inactivated serum sample was incubated with exogenic complement and B. burgdorferi ML23 pBBE22luc, which is able to process luciferin with luciferase and produce luminescence in viable Borrelia. After incubation, a light signal can be detected by using a luminometer to calculate the borreliacidal antibody titre.
    Results: Components of the reaction mixture including spirochetes and complement from various sources and concentrations were tested to identify a reliable recipe for our complement-mediated L-SBA. We also applied this L-SBA on measuring bactericidal antibody activities and calculated the half inhibitory concentration (IC
    Main limitations: Immunoreactivity of commercial complement may differ from different batches. Clinical protection of borreliacidal antibody levels has not been determined.
    Conclusions: The L-SBA provided a sensitive and easy-operating platform for the evaluation of bactericidal antibody to B. burgdorferi, and we anticipated L-SBA would function well as an evaluation tool of vaccine efficiency in the future.
